Angular dependant critical field and critical currents of epitaxial Holmium Nickel Borocarbide Thin Films — •Tim Niemeier, Ruben Hühne, Günter Behr, Ludwig Schultz, and Bernhard Holzapfel — IFW Dresden, P.O. Box 270116, 01171 Dresden
Epitaxial thin films of HoNi2B2C and related superconducting rare earth borocarbide compounds act as a suitable basis for numerous investigations on structural and superconductive properties such as Tc, Hc2 and Jc.
A new batch of HoNi2B2C thin films was grown on ceramic single crystal magnesium oxide substrates under ultra-high vacuum conditions using pulsed laser deposition. A detailed view on the deposition parameters and the physical film properties is presented and angular Hc2- and Jc-measurements are shown.
